Application filed December 19, 1907:. Serial No. 407,228.

To all whom it may concern:

Be it known that we, MATTI SARVALLA and WALTER W. SMITH, citizens of the United States, residing at De Kalb, in the county of Dekalb, State of Illinois, have invented certain new and useful Improvements in Jar- Openers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled" in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in jar openers and one object 7 of the invention s to providean implement of the class described adapted toibe used in uneapping that class of fruit jars provided with screw caps. j

With these and other objects inview'the invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in the claims, and in the drawings illustrating the preferred embodiment of the invention, Figure 1 is a bottom plan view of the improved device. Fig. 2 is a side elevation partly in section of the same. Fig. 3 isa plan view of the implement in folded position for shipping or packing. Fig. 4 is an enlarged sectional detail illustrating the manner 'of supporting the forward end of the screw.

The improved device comprises a stockB having a central longitudinal rib 6 at one side and with an aperture near one end and with an offset 20 near the other end and diver ing portions 23 leading from the base 22 of t e offset, the diver ing portions 23 having depending terminals 24 which together with the diverging portions 23 form the outer or stationary jaw of the implement. Proecting from between the tions 23 is an arm terminating ina forwardly projecting spur 25,. and attached to the base portion 22 of the ofiset is a curved cutting blade 26, the members 2526 forming portions of a can openeras' hereafter explained. The movable portion of the device is represented at A and is formed with a long1tudinal slot indicated at as, in which the rib 6 of the member B engages. The inner end of the member A is formed with an offset7 having a central bearingand continued in parallel relations to the body A as at 8 and termating in a concaved jaw portion 9 for coactlng with the jaw members 24-24, the.

ranching porconfronting faces of the portions 2424 and 9 beingserrated as shown, to increase their grip upon a can top over which they are engaged, as hereafter ex lained.

The rear end of t e member A is outturned as at and provided with a bearing in which a screw 3 is mounted for rotation, the screw having a collar 2 beyond the outturned ortion 5 and continued thence rearwardly 1n the form of a hollow handle 1, the screw being held from rearward motion by a transverse pin 5.

The inner end of the screw 3 is reduced andfits in a half bearing in the ofiset 7 and movablydis osed on the portion 8 is a .clamp member 11 flaving a laterally directed inner terminal at 14 bearing upon the reduced portion of the screw 3 and thus preventing the lateral movement of the screw while permitting its rotation. The holding member .11 is secured to the part 8 by a screw 13 and fits in a recess in the part 8 and is likewise provided with 'a knife 12 which serves as a cutting blade for a can opener, as hereafter explained- The member 11 thus performs two important functions, first as the support for the inner end of the screw 3 and second,

as a support for the can opener knife 12.

The screw 3 engages a nut 15 which bears slidably on the member A and is formed with a threaded stud 16 assing through the rib 6 and also exten ed through the aperture before mentioned in the member B, the stud provided with a wing nut 32 at the opposite side of the member B so that the nut may be clamped immovably to the member B. By this arrangement it will be obvious that when the handle 1 is rotated in one direction the screw 0 erates the nut 15 and thus moves the member A longitudinally of the member B, and compresses the can top, not shown, between the jaws 9 and 2424.

Swinging within'the hollow handle 1 is a cork screw 35.

'With a device thus constructed it will be obvious that a can top may be firmly gripped and rotated either to loosen it from the can when the contents are to be removed or to tightenit upon the can when the sealing act is to be accomplished.

The improved implement may also be employed for opemng cans of different kinds by employing the points '12 or the curved blade 26. Thus when one form of can is to be opened the point 25 is forced through the center of the surface of the end to be opened and the knife member 12 forced through the can and then the implement rotated around the point 25 as a center causing the knife 25 to cut a circular section from the can. If the can to be opened is of the oblong form such as sardine cans or the like, the curved cutting blade 26 is employed in coaetion with the adjacent portion 23 of the stationary jaw. By removing the wing nut 32 the members A and B can be separated and reversed in position as shown in- Fig. 3 and the wing nut 32 again applied to the stud .16, and thus clamp the members in their folded position, this action taking place when the implement is to be shipped or stored, or when not required for use.

The device is simple in construction, can. be inexpensively manufactured, and operates satisfactorily. for the purposes described.

What is claimed, is

1. An implement of the class described comprising a stationary body having a longitudinal guide rib and with branching arms at one end terminating in downwardly directed jaws' and with an aperture near the other end, a movable body having a longitudinal slot slidably engaging said guide rib and with a jaw element at one end and a bearing at the other end, a screw mounted for rotation in said bearing, a nut engaged by said screw and provided with a t ire-aded stud passing through the aperture of said stationary body, and a clamp nut engaging said threaded stud.

2. An implement of the class described comprising a stationary body having a longitudinal guide rib and with a clamp jau' at one end, a movable body having an op osing jauat one end and a longitudinal slot s idahly engagingsaidguiderib,aserew mounted for rotation upon said movable body, a nut through which said screw operates and provided with a threaded stud extending through said sta tionary body, and a clamp nut engaging said stud and bearing upon said stationary body.

3. An implement "of the class described comprising a stationary body having a longitudinal gulde rib and with a clam jaw at one end, a movable body having a longitudinal slot slidably engaging said guide rib and with ollsets at the ends, one of said oiisets having a half bearin and the other of said oll'sets having a whole bearing, a screw mounted for rotation in said whole bearing and with its terminal reduced and engaging said half bea rscrew within the hall" bearing, and a nut ronnected to said stationary body and through which said screw operates.

In testimony whereof, we allix our signatures, in presence of two witnesses.
